(Not > session, it does not effect anything else going through PPP at all) This sounds like a compression problem. Are both ends of the link setup to use compression, or *NOT* use compression? Earlier versions of PPP don't negotiate compression correctly, so it *may* be a compression problem. > Exact same results whether I use user mode PPP or the kernel one.

Both the user mode and kernel PPP correctly negotiate compression options, but your remote host may not. > All the hardware is unchanged from the when it was Linux, and the > clients (mostly Trumpet and Win95 systems) are unchanged as well. I would try explicitly disabling compression on the server to see if that helps. Nate
